CHAPTER 5

MULTIPLE ADAT-XT

OPERATION

OVERVIEW

By itself, a single XT provides a lot of flexibility. However, in a multiple ADAT system presents a whole new set of possibilities. Keep in mind that since the XT is an ADAT - compatible machine, you can intermingle any number of XTs and ADATs together— up to 16 machines total for 128 tracks (see the section entitled Combining XTs and ADATs on page 63). When linking multiple XTs and/or ADATs together, the first ADAT in the chain is referred to as the “master”, and the rest are called “slaves”. Each slave is locked to the master, and relies on the time reference from the master machine to keep the system synchronized.

Connections are easy to make; one 9 pin D connector for each slave. A slave will automatically detect a master and go into slave mode.

Using the 8-channel proprietary digital bus, you can also bounce tracks between machines in the digital realm. Not only does this result in a perfect copy, but one that is perfectly synchronized with the original. This means you can make perfect safety backups and archives of recordings. One creative way of using a multiple ADAT system (though it can be done with just one XT) is to dedicate two tracks of one machine for stereo mix-down. Since these mix tracks are always in sync with the rest of the system, you can execute a seamless punch at any time. For example, you could mix-down different sections of a recording independent from one another, making changes in the mix as you go along.

Each slave XT can have its own tape offset, with respect to the master machine. Combine this feature with the ability to bounce tracks in the digital domain, and you have the ability to perform cut-and-paste style assembly editing.
